- KonferenzbeitragDesigning Gaze-Aware Attention Feedback for Learning in Mixed Reality(Mensch und Computer 2022 - Tagungsband, 2022) Liu, Shi; Toreini, Peyman; Maedche, AlexanderMixed Reality (MR) has demonstrated its potential in the application field of education. In particular, in contrast to traditional learning, students using MR get the possibility of learning and exploring the content in a self-directed way. Meanwhile, research in learning technology has revealed the significance of supporting learning activities with feedback. Since such feedback is often missing in MR-based learning environments, we propose a solution of using eye-tracking in MR to provide gaze-aware attention feedback to students and evaluate it with potential users in a preliminary user study.
- KonferenzbeitragAn Immersive Learning Factory for AI & Data Literacy: An Exploratory Study in the Wild(Mensch und Computer 2023 - Tagungsband, 2023) Liu, Shi; Schulz, Thimo; Toreini, Peyman; Maedche, AlexanderArtificial Intelligence (AI) has already made a strong impact on business and private life. Nonetheless, understanding how AI works and which role data plays in this context still remains unclear for many people. We argue that students with non-technical backgrounds should build up AI & data literacy to understand the key concepts of AI & data and leverage its potential in their field of study and research. For this purpose, we present the concept of an immersive learning factory, where students can explore AI & data concepts with interactive and immersive technologies. In this paper, we demonstrate our overarching idea, as well as the results of our exploratory evaluation with industrial engineering & management students from a data science lecture. Our main contribution includes the conceptual framework of the immersive learning factory, as well as design guidelines for creating immersive learning experiences concluded from the evaluation.
- ZeitschriftenartikelPrintAssist—a conversational human-machine interface for 3D printers(i-com: Vol. 22, No. 1, 2023) Jasche, Florian; Weber, Philip; Liu, Shi; Ludwig, Thomas3D printers are no longer found only in industry, universities or makerspaces but now are increasingly used in domestic settings. Personal fabrication will increase in the coming years, and 3D printing will play an important role in this process. Due to technology and price development, 3D printers are becoming established among casual users at home. However, there are still many hurdles in the use of 3D printers that interfere with their appropriation in everyday life. In this paper, we investigate how chatbots can overcome these hurdles and support onboarding to 3D printing. Furthermore, we explore how chatbots can be used as a human–machine interface and facilitate interaction with 3D printers for both novice and expert users. In a research-through-design approach, we have created a fully functional chatbot that introduces users to 3D printing and helps them perform typical tasks when operating 3D printers.
- KonferenzbeitragSupporting the Onboarding of 3D Printers through Conversational Agents(Mensch und Computer 2021 - Tagungsband, 2021) Liu, Shi; Harun, Shahrier Erfan; Jasche, Florian; Ludwig, ThomasIn view of its capacity to create physical objects for a wide range of different potential applications, 3D printing has become increasingly popular over the years. However, given its scope of application, 3D printing can be challenging. Novice users often need assistance from experts, who are not always available. Recent interest in the development of conversational agents opens up the possibility of assisting novice users in their interactions with 3D printers, thus improving their experience. In this paper, we illustrate a potential concept of a conversational agent and present a prototype of a Telegram chatbot to improve the user experience of 3D printing.
